ABSTRACT:
The present invention provides a non-aqueous process for the dyeing of a dyeable material at an elevated temperature by contacting a dyeable material with a dye composition at an elevated temperature in a non-reactive environment. The dye composition temperature and the time of contact between the dye composition and the dyeable material are sufficient to effectuate the dyeing of the material. The dye composition comprises a substantially non-aqueous solvent and a dyestuff.
